The Broan Elite Provisa RM63700 Island Range Hood is the perfect choice for the household where cooking is the center of attention. The sleek free-hanging design of Provisa highlights a stylish focal point over any island or peninsula cook top. Its blower systems provide outstanding performance in removing grease and smoke, while halogen bulbs provide ample light. The seamless construction and fully enclosed underside assure easy cleaning.

We have a Jenn-air grill and two burners on our counter top our old fan doesn't do very well. The room fills up with smoke. We are looking at Broan Elite 637004 EX. What should we go with on External blower CFM??? Our corner top is 30 X 22. Thanks for your help>
